(Cl. 'Z2-118) 3 Claims'. 1

This invention relates to furring strips more particularly adapted forstucco-covered walls.

Anobject of the present invention is to provide new and improved meanswhereby uniformity of application of stucco or similar material to awall may be obtained without the need for great skill on the part of theplasterer.

Another object of the invention is to provide a novel and improvedfurring strip for use in supportingr one or more layers of wire mesh toprepare afwall for receiving stucco.

-Another object of theinvention is to provide wire mesh support furringfor the ultimate provision of a stucco-covered wall that resists weaveand. shock and is reproof to a high degree.

The over-all strength of a stucco wall is relatedV to the uniformity of:application of the scratch and finishing coats. An uneven primary orscratch. coat will result in a wall having strong tendencies. to crackand to yield, at its weaker parts to shock, etc. This. invention,therefore', seeks to provide simplev means, readily usable byapprentices and other relatively unskilled helpers, for preparing awallto receive uniform layers of scratch and :finishk coats of stucco.

YMy invention also has for its objects to provide such means thatv arepositive in operation, convenient in use, easily installed. in a workingposition and easily disconnected therefrom, eco-V nomical ofmanufacture, relatively simple, and of general superiority andserviceability.

The invention also comprises novel details of construction and novelcombinations and arrangements of parts, which will more fully ap.-

pear in the course of the follow-ing description.r

However, the drawings merely show andthe following description merelydescribes one embodiment of the present invention, which is givenl byway of illustration or example only.

In the drawings, like reference characters designate similar parts inthe several views.

Fig. 1- is a broken view, as seen from the outer face of a wall, showingthe manner of application of theinvention invarious stages throughthewall thickness.

Fig. 2 is an enlarged cross-sectional view as taken on the line 2-2 ofFig. 1.

Fig. 3 is a broken side view of a furring strip shown in Figs. 1 and 2.

Fig. 4 is a broken pattern view of said furring strip.

The wall, upon which the instrumentalities of the invention are applied,may be variously constructed. As shown, said wall comprises wooden studs5 covered on their outer faces by tar paper sheeting 6 or the like.

According to the invention, the wall has ap plied thereon a plurality offurring strips 'l of novel form to support a Wire mesh 8 in properspaced relation to the sheeting 6 and for the purpose of reinforcingand` guiding the uniform application of a base or scratch coat or layerof stucco or like material 9', and a plurality of furring blocks Il]mounted on said furring strips tomount and space a second wire mesh Ilfrom the'rst wire mesh for the purpose of reinforcing and. guiding theuniform applicationof a second v or ni-shing coating or layer I-.I-a ofstucco or like material.

The furring strip which is shownI in the draw-f ing,I and with moreparticular reference tofv Fig. 4, comprises, generally, an integrallight-gauge metal strip'v formed with spaced longitudinal and parallelportions I2 and longitudinally spaced connecting portions I3\. Saidstrip, along fold lines I4 and I5, is adapted to be formed` or bent, asin Figs. 2 andl 3 to provide a saddle I6 having. the shape of aninverted U` Between each pair of fold lines I4 and I5 there isdeinedfaside wall I'I having edges each formed with a-notchf I8, and betweenfold'` lines I5 there isA defined a top plate I9. The connectingportion, I3 is further formed with. tabs 2liA as longitudinal extensionsof the topl plate I9 and said tabs are' normally angularly anddownwardly directed as indicated indot-dash lines in' Fig. 3, being bentonz a fold line 2t.

Each of the longitudinal: portions I2 is provided with a plurality ofspaced holes 22V for nails 23 employedl to fasten the strip l in place.Another and optional means oi" fastening said strip, as shown in Fig. l,comprisesv av large-headed nail 24A arranged tolcatchv adjacentedges ofsaid portions I2 substantially as shown. The walls I1 are alsopreferably provided with holes 25 and the top plate i9 with a hole 26.

In practicethe strips 1, arranged in any' suit able direction, aresecu-red in place by nails i3 and/or nails 24 and the wire mesh 8 ismounted in spaced? relation to the sheeting 6 by catching portions ofsaid mesh in one notch I8 of eachy .or'most of the saddles I3, as seeninFig. 3, and

then bending the tabs 20 inward so that they serve as clinchers for themesh and also form closures for the interior of the saddle. The primaryor scratch stucco layer 9 is now applied to an approximate thicknessindicated by line 21 of Fig. 2, the closure tabs 20 keeping stucco fromfilling in the interiors of the saddles.

At a suitable time thereafter and when said scratch layer has dried, thefurring blocks I0 are mounted on as many of the saddles I3 as is thoughtnecessary. Each block may be cylindrical, as shown, or otherwise shapedand may advantageously be made of non-combustible composition material.'I'he blocks are simply nailed in place by suitably long nails 28entering through holes 26 and, in the process of nailing, the secondmesh Il is caught under the heads of said nails and thereby held inspaced relation to the scratch layer by said furring blocks. Should theholes 26 become clogged during application of the scratch layer, thenails 28 will readily dislodge such pieces of stucco to fall into theinterior areas dened by the saddle walls and the tabs 20. Since saidinterior areas are substantially free of stucco, the nails 28 meet noobstructions when being applied.

In the above manner there is provided a second outer mesh, uniformlyspaced from the already embedded inner mesh, to serve as a guide for theuniform application of a second coat r layer or an outer or finish coatlla, as desired. The line 29 of Fig. 2 suggests the outer surface ofsuch a layer.

While it is preferred to provide the furring strips as described, itwill be evident that separate individual saddles may be applied foreffecting the spaced mounting relationship of the wire meshes.

The holes 25 may be optionally employed for wire clips inter-connectingwith the wire mesh 8 to mount the same. In this disclosure and in theappended claims, the term wire mesh is intended to include reinforcingfabrics generally, examples thereof being chicken wire, expanded metal,and various types of metal fabrics..

While I have illustrated and described what I now regard as thepreferred embodiment of my invention, the construction is, of course,subject to modifications without departing from the spirit and scope ofmy invention. I, therefore, do not wish to restrict myself to theparticular form of construction illustrated and described, but desire toavail myself of all modifications that may fall within the scope of theappended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. In a wall structure, a vertical stud, a furring strip formed of sheetmetal and having longitudinally extending side strips and saddles spacedfrom each other longitudinally of the side strips, said sidestrips beingformed with openings, nails passing through said openings into the studto secure the strips against the stud, said saddles each having a atbridge, and side walls extending .from opposite side edges thereof andintegrally united with the inner side edges of the side strips, the sidewalls of the saddles having end edges formed with V-shaped recesses andthe bridge having end portions projecting beyond the side walls andconstituting tongues, a first layer of wire mesh having portions fittingabout said saddles and engaged in said recesses, said tongues being bentinwardly between the side walls and serving to hold the wire mesh in therecesses and constituting moi'- tar-excluding barriers for the ends ofthe saddles, blocks disposed against the bridge portions of certain ofsaid saddles and formed with openings registering with the openings inthe bridges, a second layer of wire mesh having portions thereon bearingagainst said blocks, and nails passing through the registering openingsof the blocks and the saddles and into the stud, the heads Of the nailsoverlapping and gripping the last mentioned wire mesh to hold the sameagainst the blocks.

2. A metal furring strip comprising longitudinally extending side stripsspaced transversely from each other, saddles spaced from each otherlongitudinally of the side strips, each saddle having a bridge and sidewalls extending from the opposite side edges thereof and integrallyunited with the inner side edges of the side strips, said side wallshaving end edges formed with recesses constituting seats adapted toreceive portions of a sheet of wire mesh, the bridges at each saddlehaving end portions extending beyond the side walls and forming tonguesbent downwardly and inwardly between the side walls and extending incrossing relation to the inner ends of the recesses in position adaptingthem to extend across the said portions of the wire mesh and secure thesame in the recesses, said tongues being of a length and width adaptingthem to t snugly between the side walls and thereby constitutemortar-excluding barriers for the ends of the saddles.
